How does this reconcile with the vast majority of people clicking “ask app not to track” when given the option? Revealed preferences can’t distinguish between things people don’t know about.
Like imagine running an experiment where in option A you get $20, and in option B you get $10. Everyone picks option A, and then the experimenter punches them all in the face because buried 50 pages into the fine print filed in the basement you didn’t know existed, it says that’s part of option A. It would be absurd to then claim “revealed preferences show that people are willing to get punched in the face for $10.”
Regardless, Meta is still allowed to do this, they just have to ask for consent now. So informed preferences will be revealed soon.
